Earlier this week we had record high temperatures in the Bay Area. Fast forward a couple of days and here comes Old Man winter.

A storm is forming over the Pacific Ocean and will make its way to landfall at some point Thursday. It will bring rain, cold temperatures and the possibility of a thunderstorm or two.

This storm will take a drier storm track, and that means it will not bring as moisture as the past few storms.

The main impact we will all feel is a dramatic 20- to 35-degree temperature drop from the record heat earlier this week.

Isolated thunderstorms may also pop up from time to time as the upper level energy will have enough uplift or “juice” to possibly fire off a few rogue cells. The best chance of thunderstorms would be Friday.

There is also a very low snow level in the Sierra with three to 10 inches of snow falling as low as 2,500 feet. There might also be a mix of rain and snow on Mount Hamilton very early Friday morning. It all depends on how much moisture is left early Friday morning when the coldest air arrives.

TIMELINE:

Thursday: Cold 50s & 60s with a chance of scattered rain from 9 a.m. into the evening

Friday: Chance of rain & isolated t-storm (any t-storm that develops may produce hail). Again scattered in nature. Temps in the 60s for daytime highs

Saturday: Few showers may linger in the morning then clearing for Sunday.
